The seoomi portion K of the ashpit under the perforated plates H is divided into two portions, a iower portion which forms the duct A connecise With'the combustion chamber B, and an upper portion k which is preferably divide into sections corresponding with the separate furnaces or cells. The upper portions is' are ivied from the hot gas cluct by a partition kihaving dempers D2 so ihat the het gases pass into one or more of the furnaces as desired. As before, a steam or other jet E or the like may be employed to xii-aw or force the hot gases into the duct A.

another form oi the invention applicabe to furnaces ieri through the top is shown in Fig. 5. rhis form is similar to that shown in Figs. 3 and 4 with the exception that the refuse or other matter is fed onto a dead plate L or the like and a perforated plate H is arranged approximately'vertically behind same so that the hot gases are oroeai through. the charge from behin. When a new charge is inserted into a iurnace ii: is place on the erforated plaie or the iihe E or the dead p ate L; the hot gas amper B2 is opened and the hot gases from the eornhustion chamber B pass -through the plate H an the new Wei; or

danp charge, and quickly drive @if all nioisture, after which it is pushed forward onto the hrighi; iire upon the re bars F and burned 'without cooling or damging the ire in an way. @r if desired the may e withdrawn Without being burneii.

nother iorrn of the invention shown in Figs. 6 anni I combinesin principle the forms shown in Figs. i and 2 5.

in iligs. i and 2 'the hoi; gases are passed into the nndivie ashpit and rise through ihe whois charge on the grate. in Figs. 3

and e, and also in Fig. 5, the ashpit is divided an@ the hoi; gases pass through only part ried matter ice of the charge on the grate, namely,A that part which rests on the-perforated plate H,

Fig. 3, or against the perforated walls H',

made in the wa s between the l ates which' lead directly to the.Y sides of t e furnaces, eparateblowers E being employedV for each uct..

The furnace may be charged either from the top or from the front, and when charged is filled up almost to the top. Thehot gases' arethen passedthrough the charge and as the moisture is dried out of it, its bulk is great y reduced and it gradually sinks down and is burned up.

When the combustion chamber is not arranged behind the furnaces as shown, the ducts -A in the walls may be arranged as branches from a common duct in a manner somewhatsimilar to that alread described. From what has hereinbefore en stated, it be clearthat I providef a chamber for the `and uincineration of refuse. This chamber is what might be considered a main or primary chamber, it comprisin in the present case several distinct portions each denoted by the character G, and in these portions the material is capable of separate treatment. For example, while the material in one of said portions is be-V can be withdrawn or otherwise of ira boiler and if there is suiiicient heat in the i gases for raising steam, and after traversing subjected to incineration or the or residual in another of portions while, in still another, the material can be dried. However, the vinvention is not limited in its embodiment to any particular num'- ber of portions in such a. main or priiiiaryf` smoke duct or passage. Generally, 'only ay small portion of the hot gases is forced by the blower back to the lires,the main porber, a secondary or combustion above indicated, this escape to they duct or passage occurring directly when the products of combustion are not used for heating a boiler. The circulation of the currents including the products of combustion is indicated by the arrows in the several figures of combustion chamber. "In the'form of em: bodiment illustrated, I provide in addition to this main or primary combustion chamchamber as B` and I have re resented a duct asleading from this auxiliary or secondary combustion chamber. This duct, therefore, isin ppsition to receive products of combustion om the combustion chamber by way of the combustion chamber, and I provide means for forcing these products of combustion through the `mass inthe main combustion chamber in which the and incineration of the refuse take place.

The foregoing description applies articularly to the forni of embodiment o invention shown in Figs. l and 2' especially, and is one way of car not reside in any specific construction, but

broadly in a refuse burner having' a. chamber to contain refuse for incineration, means i sented for receiving products of combustion from said chamber, and means. for forcing said l products of combustion through refuse supported in' said chamber. .The products of combustion thus forced through the mass of refuse eiectually and thoroughly dry the mass and act as a vehicle for carrying oft the moisture contained in said mass to the maximum heat zone of the combustion chamber and reach every 'particle or'portion of the mam and thereby avoid the labor ofstoking f or subjection of the mass to agitation.

l Iii addition to the foregoing, what I have designated as the main combustion chamber or any one of the separate refuse receiving portions may have and as shown in Figs. 3 and 5, forl example, what might. be termed a refuse part and areise combustion part to successively recei the 'lllhe refuse drying part may V:pe i wit a grate against which the refuse lilas, and this grate may have one or a plurality of openings. Infusing a. device of this type the refuse is rstplaced in the refuse drying part and dried, and after having been dried it. is moved to the refuse combustion part Vfor combustion or: incineration. InV this form of the device I takea part of the products'of combustion from the combustion chamber or at any othersuitable oint and force them through the opening in therefuse drying part and also in the mass therein, and this ope in the present case will be that pretweeii the tivo bars of said grate.

The main body of the products of combustion pass through the chamber B, and then under or around a boiler if the apparatus is applied iii such manner as to cooperate with the path mentioned the said products of combustion then pass away to` a suitable tion escaping to the duct or passage as the drawin What I c aim is:

l. A refuse burner having a chamber for the drying and incineration of refuse, means for receiving a portion of the products of V combustion passing from said chamber, and means for forcing said products of combustion through the mass in said chamber to my invention dry the same. into eifect. The invention, however, does i 1 bottom of which has openings through it, said bottom being adapted to support a mass 2. A refuse burner having a chamber the of refuse for drying and incineration, means IIC part.

for receiving products of combustion passing kfrom said chamber, and means for forcing to successively receive the refuse, means for receiving products of comibustion from said chamber, and means fr orcing said products of combustion through said opening andthrough the mass' in said refuse drying A refuse burner having a chamber provided vvith a refuse drying part and a refuse combustion part to successlvely receive the refuse,A the refuse drying part having openings for passage therethrough of the refuse drying agent, a duct in communication with and adapted to receive the productsof combustion xvhichfconstitute the drying agent from said combustionchamber, and means for causing ,the refuse drying agent to pass j through said openings under pressure to act as a drying means upon the mass of refuse while in said drying part and for subse- Y qliently liberating the said agent.

'5. A refuse burner having a combustion chamber provided With several distinct portions each to receive a body of refuse for incineration, each portion serving as an incmc'ratmg chamber'or as a drying chamber,

means. for rec'eivin a art of the roducts g P P of combustion from said combustion chamber, and means yfor forcing said products of combustion through the several portions of thev combustion chamber whereby as the operation of drying is taking place in some of the distinct portions through the instrumentality of the products of'combustion returned from the combustion chamber and passed through the Wet refuse,` incineration of the dried refuse istaking place in the other distinct portions of the combustion chamber.

' 6. A refuse burner having a combustion chamber provided with several distinct portions each to receive a body of refuse for drying and incineration, a duct for receiving products of combustion from said combustion chamber, means for forcing said prod'-A ucts of combustion through the material in said several portions of said combustion chamber, and means operable at Willfor arresting the passage of said products of combust-ion through any one of-said several portions.
